a = 0

v = 16 m/s

m = 8255 kg

p = (8255)16
p = 132080 kg*m/s
KE = 1/2mv^2
KE = 1/2(8255)(16^2)
KE = 1056640 j

These calculations assume a frictionless track and ignore air resistance.

These first calculations are not realistic bedcause the car of storm runner is traveling at 72 miles/hour but these results state that is only traveling at 36 miles/hour. I'm guessing that this was cause by a mistake in the scale made on the video. Two meters was most likely measured as one meter. Therefore, v and p would be doubled and KE would be quadrupled:
v = 32 m/s
p = 264160 kg*m/s
KE = 4226560 j
